Book excerpt: Accelerated bridge construction (ABC) using full-depth precast deck panels is an innovative technique that brings all the benefits listed under ABC to full fruition. However, this technique needs to be evaluated and the performance of the bridge needs to be monitored. Sensor networks, also known as health monitoring systems, can aid in the determination of the true reliability and performance of a structure by developing models that predict structure behavior and component interaction. The continuous monitoring of bridge deck health can provide certain stress signatures at the onset of deterioration. The signatures are vital to identify type of distress and to initiate corrective measures immediately; as a result, bridge service life increases and eliminates costly repairs This project focused on the continuous monitoring and evaluation of the structural behavior of the Parkview Bridge full-depth deck panels under loads using the sensor network installed. Special attention was placed on the durability performance of the connections between precast components. However, after careful evaluation of the designs and construction process, it was identified that the transverse joints between deck panels are the weakest links, in terms of durability, in the system. Analysis of sensor data and load test data showed that the live load effect on the bridge is negligible. The dominant load is the thermal. Using three years of data from the sensors, stress envelopes were developed. These envelopes serve as the basis for identifying the onset of bridge deterioration. A detailed finite element model was developed, and the model was first calibrated using load test data. However, due to the dominance of thermal loads, it was required to calibrate the model using stresses developed in the structural system due to thermal loads. This was a great challenge due to a lack of sensors along depth of the bridge superstructure cross-section. A few models were identified that are capable of representing the thermal gradient profile from 12 p.m. to 6 p.m. in a summer day. The FE model was calibrated using sensor data and the thermal gradient profile of the specific duration. Construction process simulation with the calibrated model shows that all the joints between the panels are in compression, as expected at the design. Stress signatures were developed simulating the debonding of a transverse joint between panels. The signatures show a distinct pattern than what is observed from a bridge without distress. Hence, the onset of deterioration can be identified from the sensor data to make necessary maintenance decisions. The proposed signatures are applicable only during noon to 6 p.m. on a summer day, and development of deterioration models for the rest of the time requires development of new thermal models. Further, the stresses vary drastically following onset of joint deterioration; hence, identification of exact physical location of the sensors is required for fine-tuning the models.

Available in PDF, EPUB and Kindle. Book excerpt: The REV conference aims to discuss the fundamentals, applications and experiences in remote engineering, virtual instrumentation and related new technologies, as well as new concepts for education on these topics, including emerging technologies in learning, MOOCs & MOOLs, Open Resources, and STEM pre-university education. In the last 10 years, remote solutions based on Internet technology have been increasingly deployed in numerous areas of research, science, industry, medicine and education. With the new focus on cyber-physical systems, Industry 4.0, Internet of Things and the digital transformation in industry, economy and education, the core topics of the REV conference have become indispensable elements of a future digitized society. REV 2018, which was held at the University of Applied Sciences in Duesseldorf from 21–23 March 2018, addressed these topics as well as state-of-the-art and future trends.

Download or read book Monitoring and Safety Evaluation of Existing Concrete Structures written by fib Fédération internationale du béton and published by fib Fédération internationale du béton. This book was released on 2003 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The condition assessment of aged structures is becoming a more and more important issue for civil infrastructure management systems. The continued use of existing systems is, due to environmental, economical and socio-political assets, of great significance and is growing larger every year. Thus the extent of necessary repair of damaged reinforced concrete structures is of major concern in most countries today. Monitoring techniques may have a decisive input to limit expenditures for maintenance and repair of existing structures. Modern test and measurement methods as well as computational mechanics open the door for a wide variety of monitoring applications. The need for quantitative and qualitative knowledge has led to the development and improvement of surveillance techniques, which have already found successful application in other disciplines such as medicine, physics and chemistry. The design of experimental test and measurement systems is inherently an interdisciplinary activity. The specification of the instrumentation to measure the structural response will involve the skills of civil, electrical and computer engineers. The main aim of fib Commission 5, Structural servicer life aspects, is to provide a rational procedure to obtain an optimal technical-economic performance of concrete structures in service and to ensure a feedback of experience gained to design, execution, maintenance and rehabilitation. Against this background fib Task Group 5.1 Monitoring and Safety Evaluation of Existing Concrete Structures had been established to evaluate the existing practice worldwide. The objective of this state-of-art report is to summarize the most important inspection and measuring methods, to describe the working process and to evaluate the applicability to structural monitoring. Particular emphasis is placed upon non-destructive systems, lifetime monitoring, data evaluation and safety aspects.
